Apple OS Update Issues

If you’ve been running a beta, or if Apple update is just confuzzled 🙂 this may help.

I was getting an error trying to update to the final version of Catalina – “The requested version of Mac OS is not Available”. Installing and removing the beta profile didn’t help.

If you have this issue, you can reset the Software Update Catalog to defaults by doing the following in terminal:

• sudo defaults delete /Library/Preferences/com.apple.SoftwareUpdate CatalogURL
• defaults delete com.apple.SoftwareUpdate CatalogURL
• softwareupdate --clear-catalog

  
  

The last one will warn about being deprecated, but still works.
Check software update again, and you should be able to download updates again.
